I think what theyre getting at is lemmy doesnt really have a good way to discover sublemmies. A lot of the subs ive found were through all when they just happened to pop up now and again rather than specifically searching for a particular topic. Thats not a very fast way to find new communities. Which you could argue reddit doesnt do a great job of it either but lemmy is in a position where it cant afford to be inefficient.
You can search for communities and subscribe to them. Then you can select “subscribed” instead of “local” or “all”
